Scientific project

LISAH's research aims at the systemic analysis of cultivated landscapes functioning.

To this end, a major scientific stake is understanding and modelling the relations and interactions between biophysical processes - i.e. hydrological, bio-geographical and ecological - and the landscape characteristics, be they "natural" (soil, landform) or linked to farming activities (plot organisation, crops, agricultural practices, hydro-agricultural infrastructures, ...).

Our research are thus based on the idea that the analysis of landscape functioning requires advancing simultaneously our understanding of mass transfer processes and of the determinants of spatial organization and evolution of properties of cultivated areas.  
Following  this approach, research  is carried out within  the three following teams:

In addition to these teams there are two Transversal Program (TP) : the TP "agro-hydrological observations in cultivated landscapes"  and the TP "Agro-environmental engineering of cultivated landscapes".

  • The TP "agro-hydrological observation in cultivated landscapes " aims to contribute to the lab strategy for fluxes and agro-systems characteristics (e.g. soils, agricultural practices) observations, surveys and measurements necessary for the scientific issues addressed by the lab. One of the TP priorities, not exclusive of others, is to define the strategy, the needs and  methods of observation in connection with our research  to the spatial mesoscale (ca. 100 km-2)
  • The TP "Agro-environmental engineering of cultivated landscapes" addresses the needs to share those approaches developed within the Unit concerning the tools and methods to design scenarios of landscape mosaics evolution. These scenarios correspond to new management modes for landscape and water and soil resources, modes that optimize the functions and/or ecosystem services of the  studied landscape.  These scenarios must take into account and exploit the overall climatic and economic drivers, the environmental heterogeneities, the stakeholders' know-hows and constraints, and the innovative capacities both external and internal. Their development involves that of landscape evolution models defining changes in soil uses and spatial allocation, models that allow the joint evaluation of landscape functions and services.
